Annual herb from a taproot; stems erect, slender, simple or few-branched, hairless or glandular-hairy or obscurely white-woolly, 15-100 cm tall.
Basal leaves pinnately cleft, the lowermost 1 to 2 times pinnately cleft with slender axis and narrow ultimate segments 1-15 mm long, 1-2 mm wide; stem leaves similar to the basal, alternate, reduced upwards, the axils and midribs generally white-hairy.
Inflorescences dense, ball-like clusters of 50 to 100 stalkless flowers, the clusters on long bractless stalks terminating the stem and branches; corollas pale blue, 6-10 mm long, the tube flaring to five linear-oblong (1 mm wide) lobes about as long as the tube; calyces expanded in fruit, the five lobes pointy-tipped.
Capsules, egg-shaped to spherical, with three 1- to 3-seeded chambers; seeds 1.5 mm long, becoming sticky when moistened.
